providing the timing feature and also generating a timing signal to
the first processing unit 21; the memory unit 25 allowing to store
default information and signal information, in which the default
information may include the electric power cost information, power
consumption and carbon footprint and other relevant information,
and the signal information indicates the information included
within the second wireless signal transmitted from the electric
socket device 30; a first wireless module 26 is able to receive a
second wireless signal and transmit it to the first processing unit
21, or alternatively receive the second control signal from the
first processing unit 21 so as to send a first wireless signal; and
a temperature detecting unit 28 is able to detect the ambient
temperature and accordingly generate a temperature detection signal
to the first processing unit 21.
[0016] The electric socket device 30 comprises: a power input
device 35 connected to a power line network (not shown) through an
electric power cord (not shown) and an electric plug (not shown); a
surge protection unit 34 enabling a surge protection feature; a
switch unit 33 allowing to receive a power signal and transmit the
power signal to the power output unit 32, thereby enabling the
switch unit 33 to control the power supply of the power output unit
32; a second processing unit 31 generating a third control signal
to control the ON or OFF status in the switch unit 33, and also
generating a fourth control signal to control a second wireless
module 36 to emit a second wireless signal; and the second wireless
module 36 also receiving a first wireless signal and transmitting
to the second processing unit 31. Herein the power output unit 32
may include a plurality of electric sockets, and the switch unit 33
is allowed to individually control providing or stopping power
supply to the plurality of electric sockets.
[0017] The power management apparatus 20 may be also enabled to
collect power consumption in the electric socket device 30 and
convert the collected power consumption into information relating
to electricity fees or carbon footprint. The second processing unit
31 in the electric socket device 30 computes power consumption
statistics by means of the switch unit 33 and then transfers to the
first processing unit 21 in the power management apparatus 20; the
first processing unit 21 executes computations incorporated with
the default information installed within the memory unit 25,
thereby accordingly controlling the display unit 23 to show
information, e.g., power consumption, payable amount, carbon
footprint and so forth, for each or the plurality of electric
socket devices 30.
[0018] The power management apparatus 20 may be also configured
with the function of power supply management on the electric socket
device 30. The input unit 22 receives the setup signal inputted by
the user, and compares the setup signal through the first
processing unit 21 with the power consumption information in the
electric socket device 30. Thus, the power management apparatus 20
controls the electric socket device 30 to stop power supply when
the accumulated power consumption is greater than or equal to the
upper limit of the power consumption indicated in the setup signal.
Similarly, the user is also allowed to input the setup signal
indicating the upper limit amount of the electric power cost or the
carbon footprint etc., so as to effectively perform energy
management on each or the plurality of electric socket devices
30.
[0019] The power management apparatus 20 may be also capable of
providing a feature of temperature detection and management. The
temperature detecting unit 28 in the power management apparatus 20
detects ambient temperature, and accordingly generates a
temperature detection signal. The first processing unit 21 receives
such a temperature detection signal and has it displayed on the
display unit 23. Furthermore, based on a temperature setup signal,
it is possible to control the power output unit 32 to provide power
for driving an appliance, and to initiate different appliances,
e.g., an air conditioner or an electrical fan, in accordance with
various temperatures.
[0020] Additionally, the power management apparatus 20 may be
configured with a feature of power supply cycle. The user is
allowed to input a setup signal containing the time information,
and the first processing unit 21 compares the setup signal with the
time signal generated by the time unit 24. Hence, the power
management apparatus 20 is enabled to control the power supply
cycle for each or the plurality of the electric socket devices 30
based on the comparison result of the setup signal and the time
signal.
[0021] The power management apparatus 20 may be able to provide a
function of power cut-off timing as well. Upon the occurrence of
power outage, the start time of the power cut-off can be shown on
the display unit 23 and the time unit 24 begins to count. As soon
as power supply is received once again, the power management
apparatus 20 then displays both the end time of the power cut-off
and the elapsed duration for the power cut-off.
[0022] The power management apparatus 20 may facilitate surge
protection feature. A surge protection unit 34 is connected between
the power input unit 35 and the switch unit 33, thereby absorbing
or blocking the unwanted surge signals. Besides, the second
processing unit 31 may read out relevant surge information
concerning the absorption or blockage in the surge protection unit
34. The power management apparatus 20 subsequently performs
statistical operations and categorizes in accordance with the
magnitude of such surge signals in Joules displayed on the display
unit 23.
[0023] The power management apparatus 20 may control the plurality
of electric socket devices 30. The power management apparatus 20 is
allowed to perform wireless signal transmissions with the plurality
of electric socket devices 30 simultaneously via the first wireless
module 26, thereby controlling the plurality of electric socket
devices 30, collecting relevant information regarding the plurality
of electric socket devices 30, and respectively or collectively
displaying information concerning the plurality of electric socket
devices 30 and the like.
[0024] Next, referring conjunctively to FIGS. 2 and 3, in which the
smart power management system 2 comprises a power management
apparatus 20, a plurality of electric socket devices 30, 30' and a
plurality of electric sockets 32a, 32b, 32a', 32b'.
[0025] After startup of a computer 15, a television set 16 or an
air conditioning system 17, the electric socket device 30, 30'
respectively transfers the conditions about power consumption,
surge protection etc. currently exhibiting in individual electric
sockets 32a, 32b, 32a' to the power management apparatus 20, which
are shown on the display unit 23.
[0026] The power management apparatus 20 can control the plurality
of electric socket devices 30, 30' based on the setup signal
inputted by the user such as time information, power consumption
information or temperature information, within a specific period of
time or else under a certain condition of power consumption or
temperature.
[0027] Refer now to FIG. 4, wherein the power management apparatus
40 includes a network module 27. That is, the first processing unit
21 is allowed to be connected to a network system 51 by means of
the network module 27 to access information required.
[0028] Therefore, the power management apparatus 40 can obtain in
real time the power cost information via connections to the power
company by means of the network system 51, and has the most recent
information about electricity fees or carbon footprint information
displayed. Besides, it is also possible to remotely access and
control the power management apparatus 40 through the network
system 51.
[0029] Referring conjunctively to FIGS. 4 and 5, in which the smart
power management system 3 comprises a network system 51 in
connection with a power management apparatus 40. Consequently, the
power management apparatus 40 is enabled to automatically link to
the power company through the network system 51 for acquiring
information concerning the most up-to-date electric power cost and
carbon footprint. Thus, the power management apparatus 40 can
accordingly provide the most accurate information in terms of
electric power cost and carbon footprint.
[0030] Furthermore, the user is able to control the power
management apparatus 40 remotely via the network system 51, and
also allowed to remotely access information such as the conditions
regarding power consumption, surge blockage . . . and so forth
stored in the power management apparatus 40 through the network
system 51.
